  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 (1) is a front view showing an intelligent card holder according to one embodiment of the present invention, FIG. 1 (2) is a block diagram of a main part of the intelligent card holder according to one embodiment of the present invention, and FIG. FIG. The ID cards 10 and 11 are, for example, identification cards and employee ID cards, and perform authentication for holders to enter rooms or facilities where it is necessary to prevent illegal intrusion. As shown in FIG. 2, the ID cards 10 and 11 are inserted from the rear side insertion opening of the main body 1.

  The intelligent card holder according to the present invention can exhibit some functions by itself, but when used together with the smartphone 20, it can exhibit advanced functions. That is, the intelligent card holder according to the present invention has a function of wirelessly communicating with the smartphone 20, and can be controlled by the application installed in the smartphone 20.

  The ID cards 10 and 11 are, for example, identification cards and employee ID cards using general-purpose plastic cards, and perform authentication for the owner to enter a room or facility where it is necessary to prevent illegal intrusion. Needed for. Each of the ID cards 10 and 11 is an IC card in which a semiconductor chip is mounted and information can be stored or rewritten, and an RFID tag is used for authentication. A photograph, a name and the like are additionally written on the surface of the ID card 10 and 11. Then, the wearer of the ID card carries it by hanging it from the neck with a string through the hole 8 of the handle 7 provided in the main body 1.

  At least the surface of the main body 1 is a transparent resin having high transparency, for example, PC (polycarbonate / polycarbonate), PET (polyethylene terephthalate / pet), PVC (polyvinyl chloride / vinyl chloride), PMMA (polymethyl methacrylate / acrylic), etc. Created in. The ID cards 10 and 11 are installed so that the surface thereof faces the surface of the main body 1. A functional liquid crystal film 2 is attached to the front side of the main body 1, between the ID cards 10 and 11 and the front side of the main body 1, and on the front side of the main body 1. The functional liquid crystal film 2 is a film that can be instantly switched between transparent and opaque (for example, cloudy) by turning the power on and off.

  A control board 3 is provided on the upper part of the main body 1, and the control board 3 has a function of switching between transparent and cloudy of the functional liquid crystal film 2 and Bluetooth (registered trademark), Wi-Fi (registered trademark) or LTE. A transmission / reception unit 100 having a function of communicating with a smartphone (multifunctional mobile phone) by a wireless communication protocol such as (Long Term Evolution), and a handover function for simplifying a connection procedure with the smartphone (multifunctional mobile phone). It has a corresponding NFC interface 102 and a control unit 104 for controlling the whole.

  Therefore, when communicating between NFC-compatible devices, only connection procedures such as pairing and authentication can be performed by NFC, and actual communication can be taken over by higher-level Bluetooth (registered trademark) or Wi-Fi (registered trademark). it can. Usually, a procedure such as inputting authentication information is required for pairing and authentication, but if NFC is used, the connection can be completed by simply holding the smartphone (multifunctional mobile phone) over the main body 1. Here, it is not always necessary to have the function of NFC, and it may be configured by only Bluetooth (registered trademark) or Wi-Fi (registered trademark). In that case, the NFC interface 102 becomes unnecessary.

  Reference numeral 4 denotes a 3-position switch, which has the functions of OFF, ON (1), and ON (2). OFF turns off the power supply to the functional liquid crystal film 2, and ON (1) turns on the power supply to the functional liquid crystal film 2. ON (2) turns on the power supply to the functional liquid crystal film 2 and turns on the lights 5 and 6 provided on the functional liquid crystal film 2 and the ID cards 10 and 11 to illuminate.

  As described above, the main body 1 turns on / off the power supply of the functional liquid crystal film 2, that is, the functional liquid crystal film 2 is switched between transparent and opaque by the switch operation on the main body 1 regardless of the communication with the outside. be able to.

  A battery 9 supplies power to the control board 3 and the lights 5 and 6. The battery 9 can be charged from an external power source and has a female terminal of USB Type-C or USB Micro-B. The capacity is such that the switch 4 can be continuously operated for 18 hours or more or 24 hours or more in the ON (2) state.

  3 and 4 are diagrams for explaining the principle of the functional liquid crystal film 2. FIG. 3 shows a state when the power is off and the liquid crystal is cloudy, and FIG. 4 shows a state when the power is on and the liquid crystal is transparent. The polymer 2-6 is formed between the two plastic films 2-1 and 2-2 in a network form, in which the liquid crystal molecules 2-5 are irregularly arranged, and the transparent electrodes 2-3 and 2- are provided at both ends. 4 are provided.

  When the power is off and no voltage is applied to the transparent electrodes 2-3 and 2-4, the randomly arranged liquid crystal molecules 2-5 scatter light and become opaque and cloudy. When the power is turned on and a voltage is applied to the transparent electrodes 2-3 and 2-4, the irregularly arranged liquid crystal molecules 2-5 are arranged perpendicularly to the transparent electrodes 2-3 and 2-4 and transmit light. It becomes transparent.

  Therefore, the ID cards 10 and 11 become opaque when no voltage is applied to the functional liquid crystal film 2, and the information displayed on the ID cards 10 and 11 cannot be seen from the outside of the main body 1. If the functional liquid crystal film 2 is not applied with a voltage when the carrier goes out of the facility, even if the ID cards 10 and 11 have personal information such as a photograph or a name displayed on the surface, the personal information You can avoid inadvertent exposure.

  In addition, when the functional liquid crystal film 2 is applied with a voltage when entering the facility, the information is displayed on the ID cards 10 and 11 as usual, so that the user can confirm. The intelligent card holder body 1 is designed to accommodate two ID cards 10 and 11, but it may be one ID card 10 and will be described as one ID card 10 below.

  FIG. 5 is a diagram showing a state where the intelligent card holder body 1 and the smartphone (multifunctional mobile phone) 20 are communicating with each other. By transmitting an instruction signal to the control board 3 using the function of the smartphone 20 while the communication connection is established, the functional liquid crystal film 2 can be switched between transparent and cloudy. That is, the control board 3 makes the functional liquid crystal film 2 cloudy by receiving an instruction signal from the external device with a communication function from the smartphone 20 as necessary. Since the shutter closes the personal information such as the photograph and name provided on the surface of the ID card 10 due to the cloudiness, it is possible to prevent the other person from easily viewing the information. It is needless to say that the expression "white turbidity" here means opacity, and opacity may be achieved by a method different from white turbidity.

  Further, when the intelligent card holder body 1 is separated from the smartphone 20 by a predetermined distance, a buzzer (not shown) provided in the intelligent card holder body 1 sounds and the functional liquid crystal film 2 becomes cloudy, that is, the ID card 10 This means that the shutter for the personal information on the photo or name on the surface was closed so that it could not be viewed.

  At this time, instead of the intelligent card holder body 1, the smartphone 20 may emit a warning sound such as a buzzer. Alternatively, a warning sound such as a buzzer may be emitted from the smartphone 20 at the same time as the intelligent card holder body 1.

  Here, various existing methods can be adopted as a method of detecting that the object is separated by a predetermined distance. For example, it is assumed that the intelligent card holder body 1 and the smartphone 20 are separated from each other by a predetermined distance when they are unable to receive communication radio waves from each other, or when the intensity of the received signal is below a predetermined value. be able to.

  Furthermore, the location or position (also referred to as a lost location) where the intelligent card holder body 1 and the smartphone 20 are separated by a predetermined distance or more, and the time at that time are the time information provided by the smartphone 20 and the position information by the GPS function ( It is determined based on (GPS information) and stored in the smartphone. As a result, even if the intelligent card holder body 1 is dropped or lost, the position where the intelligent card holder body 1 is separated from the smartphone 20 by a predetermined distance is stored in the smartphone 20. It will be easier to find.

  Here, the position information may be obtained not only from the GPS function but also from another function for knowing the position. This is true in all what is described below using GPS information. For example, when the smartphone 20 is connected to wireless communication such as Wi-Fi (registered trademark), the position can be obtained from the information of the connected wireless communication router and access point, and the information can be obtained from the information. It is also possible to set the lost location as the lost location. In this method, when the area of the wireless communication access point is finely determined in the building, the position can be accurately determined, and the position information can be effectively known even in the building where the GPS signal cannot be obtained. You can Here, in the present invention, the means for knowing all other positions including the GPS function and the function for obtaining the position as described above is also referred to as position calculating means.

  Furthermore, not only when the intelligent card holder main body 1 is separated from the smartphone 20 by a predetermined distance, but also the functional liquid crystal film 2 becomes cloudy depending on the location based on the position information (GPS information, etc.), that is, the shutter is closed to close the ID card 10. It becomes possible to hide the personal information such as the photograph and name provided on the surface.

  For example, by registering one's own company as a predetermined position, the smart card 20 sends a signal to the intelligent card holder body 1 to the effect that the smartphone 20 has left the predetermined position when leaving the company's premises, The control unit 104 makes the functional liquid crystal film 2 cloudy. On the contrary, by entering the site of the company, the smartphone 20 sends a signal to the intelligent card holder body 1 to the effect that the smartphone 20 has entered a predetermined area, and the control unit 104 of the intelligent card holder body 1 causes the functional liquid crystal film 2 To make it transparent. As a result, it is possible to prevent others from seeing personal information such as name and photo, which is the contents of identification card, etc. outside the company, and at the same time, it is possible to show the ID card to the inside company inside the company. ..

  Although described as the smartphone 20, any device capable of communicating with the intelligent card holder body 1 may be a tablet or a dedicated external device. These external devices (intelligent card holder body such as smartphones and tablets) may be used. 1 (including all devices capable of wireless communication with 1), the functional liquid crystal film 2 can be switched between transparent and cloudy, that is, shutter control for the ID card 10 can be performed.

  Further, the smartphone 20 and other external devices capable of controlling the functional liquid crystal film 2 of the intelligent card holder body 1 can be limited to those authenticated by the intelligent card holder body 1.

  As a result, even if another person happens to invade a company or the like by holding the acquired intelligent card holder body 1, if the other person does not have the smart phone 20 authenticated by the intelligent card holder body 1, the intelligent card holder body 1 Maintains the cloudy state of the functional liquid crystal film 2, assuming that there is no authenticated smartphone 20 nearby.

  Therefore, if there is a person who hangs the cloudy state of the intelligent card holder body 1 from the neck in the company, it can be easily identified as a person who has entered the company without permission. Further, when an intruder into a company or the like intrudes while holding a fake intelligent card holder body 1, the security guard and the administrator operate the functional liquid crystal film 2 of the intelligent card holder body 1 with an external device. It is possible to identify whether an intruder or not.

  That is, since the fake intelligent card holder body 1 does not react to the external device possessed by the guard or the administrator, even if the guard operates the external device, the functionality of the fake intelligent card holder body 1 is improved. The liquid crystal film 2 does not change. As a result, the security guard can easily identify whether or not he is an intruder. By operating with an external device, not only the functional liquid crystal film 2, but also the buzzer ringing, lighting on / off, etc. can be performed as described later, and security personnel and managers can perform these operations. The intruder can also be identified by whether or not it is.

  FIG. 5 shows a screen on which an application installed on the smartphone 20 is activated. In this state, by inputting the ID into the ID input unit 21 and the password into the password input unit 22 and pressing the enter key 23, communication between the intelligent card holder body 1 and the smartphone 20 is established. In addition, on the screen of the application, a PIN key 24 for inputting a PIN (personal identification number), a buzzer key 25 for ringing a buzzer provided in the intelligent card holder body 1, and an illumination key for turning on the lights 5 and 6 for illumination. 26, the functional liquid crystal film 2 is provided with a white turbidity, a transparency, that is, a time setting key 27 that determines the opening and closing time of the shutter.

  The ID card carrier sets the PIN in the intelligent card holder body 1 with the PIN key 24, so that even if someone who does not know the PIN turns the switch 4 ON (1), the functional liquid crystal film 2 is transparent, that is, You can prevent opening the shutter. Further, if the PIN is not input to the smartphone 20, it is possible to prevent the functional liquid crystal film 2 from being switched between transparent and opaque from the smartphone 20. Furthermore, when the intelligent card holder body 1 is left behind, the buzzer key 25 can be struck to find it.

  Further, at night, the lights 5 and 6 can be turned on by the illumination key 26 so that the ID card can be easily confirmed. With the time setting key 27, the shutter is opened during business hours (regular time), and the shutter is closed after the scheduled time passes, so that careless display of the ID card is eliminated and personal information can be sent to a third party. It can be prevented from leaking.

  The position of the intelligent card holder body 1 is determined by GPS information or the like by the smartphone 20. Further, a program for controlling the functional liquid crystal film 2 as a shutter is incorporated in the application installed in the smartphone 20. Therefore, by previously registering the location (position) of opening and closing the shutter in the application, it becomes possible to control the opening and closing of the shutter according to the location by using GPS information. For example, as a place to open and close the shutter, it can be automatically registered as an exit of a facility, a company, etc., and when the carrier leaves the exit, the shutter can be closed based on the GPS information.

  Further, since the ID of the carrier is input to the application, it is possible to register the specific other person ID, keep the shutter closed at all times, and display the ID card 10 only to the specific other person. That is, the shutter is opened when it is detected that the registered mobile phone users are approaching each other. As a result, it is possible to further enhance security against leakage of personal information and the like.

  Furthermore, the smartphone 20 carries not only the ID card carrier but also a security guard, for example. Then, the guard is registered in the plurality of intelligent card holder bodies 1 as an administrator. Thereby, if the guard uses the dedicated external device or activates the application installed in the smartphone 20 carried by the guard, the shutter of the functional liquid crystal film 2 of the intelligent card holder main body 1 can be set. It is possible to open and turn on the lights 5 and 6.

  FIG. 6 is a diagram showing the relationship between the personal authentication and the smartphone 20 and the intelligent card holder body 1. An NFC device 500 that communicates with the smartphone 20 having an RFID tag to perform personal authentication is installed at the entrance of a facility or the like, or the entrance of a living room on each floor. The NFC device 500 is a wireless interface having a communication distance of about 0 to 20 cm, and may be attached to the wall surface 800, a flapper gate 801 having a flap 802, or the like. When the flap 802 is attached to the flapper gate 801, door opening / closing of the flap 802 is controlled according to the result of personal authentication.

  The NFC device 500 has a communication terminal 505, and when the NFC device 500 has an authentication result display unit, it has a screen 504 for displaying the authentication result. The user performs personal authentication by holding the portable smartphone 20 over the communication terminal 505. If the authentication is OK, the fact that the authentication is OK is displayed on the screen 504. In the flapper gate 801, the flap 802 is opened in cooperation with the authentication OK.

  Since the smart phone 20 recognizes the ID, the smart phone 20 returns a response to the NFC device 500 without inputting the ID to the application, that is, after the passive communication mode by the RFID is established, Bluetooth (active communication mode) is established. Communication is automatically established between the smart phone 20 and the intelligent card holder body 1 by a wireless communication protocol such as a registered trademark), Wi-Fi (registered trademark), or LTE (Long Term Evolution). Then, the shutter of the functional liquid crystal film 2 is controlled to open when the facility or the room on each floor is entered.

  In the above description, the smartphone 20 is held over the communication terminal 505 to perform personal authentication, but the application is activated first to establish communication between the smartphone 20 and the intelligent card holder body 1. You can go. In this case, the intelligent card holder body 1 may be held over the communication terminal 505 to perform personal authentication.

  Next, a program for controlling the intelligent card holder of the present invention from an external terminal such as the smartphone 20 will be described. This program can be installed in the smartphone 20 as an application and used.

  This program causes a computer mounted on an external terminal such as the smartphone 20 to function as a means for controlling the intelligent card holder. The smartphone 20 will be described below as an example of the external terminal.

With this program, the computer of the smartphone 20 operates as follows.
That is, the computer stores the predetermined position information in the memory of the smartphone 20 (step 1). As the predetermined position information, for example, the current position information obtained from the GPS device mounted on the smartphone 20 can be stored as the predetermined position information.

  In addition, the computer is manually input from the input device of the smartphone 20 (the input keyboard displayed on the display screen, the communication device mounted on the smartphone 20, or the like), or as an electronic mail or by another method. Latitude / longitude information can be stored as predetermined position information.

  The computer also acquires the current position information from the GPS device mounted on the smartphone 20 (step 2). Next, the computer compares the current position information with the predetermined position information, and determines whether the position indicated by the current position information is more than a predetermined distance away from the position indicated by the predetermined position information. It is calculated and judged (step 3).

  Here, whether or not the distance is equal to or more than a predetermined distance can be determined by calculating a distance between two points from two pieces of latitude / longitude information and comparing the result with a numerical value of the predetermined distance. Here, the predetermined position information may be two-dimensional information indicating a certain area, instead of the one-dimensional point. In that case, information indicating the area can be represented by latitude / longitude information of a plurality of points and information about the order in which the points are connected.

  In this case, the area of the company or factory can be represented by connecting the sites of the company or factory with a plurality of points, and the computer determines whether the current position is outside or inside the area, and based on that, various You may make it operate | move. Therefore, the step 3 is "the computer compares the current position information with a plurality of position information indicating the range of the predetermined area, and determines whether the current position is within the range of the predetermined area or out of the range. Yes. "

  In addition, the computer controls the communication device mounted on the smartphone 20 based on the determination in step 3 to instruct the control board 3 of the intelligent card holder to switch between transparent and opaque of the functional liquid crystal film 2. A signal is transmitted (step 4).

  In addition, this program may perform the following operations. That is, the computer receives an input from a person who uses the smartphone 20 (step 10). The smartphone 20 has an input means as a standard, which is, for example, a keyboard displayed on the screen of the smartphone 20 or a screen for flick input.

  Although these may be used, it is preferable that the computer displays a dedicated screen for accepting an input on the screen of the smartphone 20 and the user taps the screen to input. For example, a method of displaying a transparent / opaque changeover switch of a functional liquid crystal film or a buzzer ringing button and inputting by tapping it is simple and more preferable.

  Next, the computer controls the communication device mounted on the smartphone 20 based on the content of the input from the input means to switch the transparent / opaque functional liquid crystal film 2 to the control board 3 of the intelligent card holder. And (2) sounding a buzzer mounted on the intelligent card holder, or both (step 20).

  For example, when the transparent / opaque changeover switch displayed on the screen is tapped, the computer instructs the control board 3 of the intelligent card holder to change the transparent / opaque state of the functional liquid crystal film 2. A signal can be transmitted. Further, the computer can send a signal instructing the control board 3 to ring the buzzer mounted on the intelligent card holder when the buzzer ringing button displayed on the screen is tapped. ..

Further, this program may cause a computer to perform the following operation.
That is, when the communication between the communication device mounted on the smartphone 20 and the control board 3 is interrupted, the computer acquires the position information at that time from the GPS device mounted on the external terminal and uses the smartphone 20 as lost position information. In the memory (step 100).

  Next, the computer receives an input from a person who uses the external terminal (step 102). This is preferably a method in which the computer displays a dedicated screen for accepting the input on the screen of the smartphone 20 and the user taps the screen to input. For example, the method of displaying the button indicating the lost position of the intelligent card holder on the screen and inputting it by tapping it is simple and more preferable.

  Based on the input content in step 102, for example, when the intelligent card holder lost position display button displayed on the screen is tapped, the lost position information is displayed on the screen of the smartphone 20 (step 104). The display may be displayed as latitude and longitude information, but this is difficult to understand. Therefore, it is preferable to display a map and display a predetermined mark at the point indicated by the lost position information on the map.

  Although the smartphone 20 has been described as an example in the above description, it is not limited to the smartphone, and any external device (also referred to as an external terminal) capable of communicating with the intelligent card holder body 1 may be used instead of the smartphone 20. The same effect as the smartphone 20 can be obtained. Here, some of the external devices include not only portable terminals such as tablets, notebook computers, and special external devices manufactured exclusively for communication with the intelligent card holder body 1 but also stationary types that are difficult to carry. A PC is also included.
